Bear with me......

I bought my 55 plate 1.9TDI PD 100 BORA, from the car people in september 06, with 13000 miles on the clock. They told me they had done a full service and used longlife oil, and the car would tell me when the next service was due.

Turned my car ignition on this morning and a message comes up with "service due in 2000 miles". Having only covered 3500 miles from when i picked it up, i thought it a bit strange that an apparantly a longlife service only lasts 5500 miles.

I came to the conclusion that when they serviced it, they didn't reset the ecu. So i took it back to the car people today and they cleard the message for me.

Now, when i got the car back, there was a print-out on the passenger seat that had the directions to reset the service message, and a disclaimer that said if my vehicle was on a Long Life services it can only be done with diagnostic equipment, and i think they have reset as normal service (if that makes sense)

My question's are ....(eventually) how will this affect the car's ECU, and is the "normal" reset just a counter for milage on time.

Thanks for any help in advance.....
